[PATCH] D40213: [x86][icelake]BITALG

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

Can you add command lines to vector-tzcnt-128/256/512.ll? We should be able to use popcnt for tzcnt when avx512cd's lzcnt is not available.

----------------
Remove one these blank lines. There shouldn't be 2.
